Self-interest overrides rank-reversal aversion in resource distribution

Area of Science:

• Behavioral Economics
• Social Psychology
• Neuroscience

Background:

• Equitable resource allocation is a key human concern, driving research into distributive justice.
• Inequality aversion is a known motive, but rank-reversal aversion presents a conflicting perspective.
• The influence of self-rank on rank-reversal aversion remains underexplored.

Purpose of the Study:

• To investigate rank-reversal aversion in a first-party context (when self-rank is present).
• To explore diverse moral strategies individuals employ in resource distribution.
• To understand how self-rank modifies rank-reversal aversion's impact on behavior.

Main Methods:

• A modified redistribution game was employed with 55 online-recruited participants.
• Participants' decisions were analyzed under conditions of stable versus altered self-rank.
• Behavioral patterns were categorized to identify distinct moral distribution strategies.

Main Results:

• Rank-reversal aversion was observed when participants' self-rank remained unchanged.
• When self-rank was altered, participants' behavior shifted to reflect their new ranks.
• Individual differences emerged, leading to the identification of three moral strategies incorporating rank-reversal considerations.

Conclusions:

• Rank-reversal aversion influences distribution behavior, particularly when personal rank is maintained.
• The impact of rank-reversal aversion is modulated by changes in self-rank.
• Understanding these dynamics offers insights into political and economic resource allocation strategies.
